The emerald ash borer (EAB), Agrilus planipennis, is a highly destructive quarantine pest. The olfactory and visual systems of A. planipennis play different but critical roles at newly emerged and sexually mature stages; however, the molecular basis underlying these differences remain unclear. Consequently, based on deep transcriptome sequencing, we evaluated the expression levels of chemosensory-related proteins and opsins at the two developmental stages of A. planipennis. We found 15 new chemosensory-related genes in our transcriptome assembly compared with the previous genome assembly, including 6 that code for odorant-binding proteins (OBPs) and 9 for chemosensory proteins (CSPs). The expression of several chemosensory-related genes (OBP7, OBP10, CSP1, and CSP12) differed markedly between newly emerged and sexually mature A. planipennis. We also found that the expression of UV opsin 2 and LW opsin 1 was higher in sexually mature male A. planipennis, which may be associated with their strong visual mate detection ability. This study forms the basis for further investigation of the chemosensory and visual system of A. planipennis, and these differentially expressed genes between newly emerged and sexually mature stages may serve as targets for the management of this destructive forest pest after sexual maturity.

翡翠灰bore（EAB）， 平菇，是高度破坏性的检疫性有害生物。嗅觉和视觉系统拟南芥在新兴和性成熟阶段扮演不同但至关重要的角色；然而，这些差异背后的分子基础仍然不清楚。因此，基于深度转录组测序，我们评估了化学感应相关蛋白和视蛋白在两个发育阶段的表达水平。拟南芥。与先前的基因组程序相比，我们在转录组程序集中发现了15个新的化学感应相关基因，包括6个编码气味结合蛋白（OBP）和9个化学感应蛋白（CSP）。几种化学感应相关基因的表达（OBP7，OBP10，CSP1和 CSP12）新出现和性成熟之间明显不同 拟南芥。我们还发现紫外线视蛋白2 和 LW视蛋白1 性成熟的男性更高 拟南芥，这可能与其强大的视觉伴侣检测能力有关。这项研究为进一步研究小鼠的化学感觉和视觉系统奠定了基础。拟南芥，并且这些在新出现和性成熟阶段之间差异表达的基因可能成为性成熟后管理这种破坏性森林害虫的目标。
